Summary
Individuals with low back pain (LBP) shift their posture more frequently during prolonged sitting than asymptomatic individuals. Increased movement did not reduce pain for those with LBP.
Area of Science:
- Biomechanics
- Ergonomics
- Pain Management
Background:
- Prolonged sitting and lumbar spine flexion are linked to low back pain (LBP).
- Understanding how lumbar spine movement affects mechanical changes and injury risk during sitting is limited.
Purpose of the Study:
- To compare postural responses and pain in LBP sufferers versus asymptomatic individuals during prolonged sitting.
- To identify biomechanical factors contributing to sitting-induced LBP.
Main Methods:
- 16 participants with sitting-aggravated LBP were matched with 16 asymptomatic participants.
- Tri-axial accelerometers monitored lumbar spine angles during 90 minutes of seated computer work.
- Movement patterns, including shifts and fidgets, were analyzed.
Main Results:
- LBP group reported significant pain increases; asymptomatic group reported minimal pain.
- All participants fidgeted frequently, but LBP sufferers showed significantly more shifts over time.
- LBP sufferers exhibited larger amplitude shifts and fidgets compared to the asymptomatic group.
Conclusions:
- Increased and more frequent movement did not alleviate pain in individuals with LBP.
- Further research into the biomechanical effects of proactive movement is needed to understand the movement-pain paradox.
